We retrospectively analyzed 218 allergen skin prick tests ( SPT ) of the patients with chronic sinusitis with or without nasal polyps( CRSwNP/CRSsNP) before the operation. The proportions of positive SPT in CRSwNP and CRSsNP were compared respectively. The distributions of allergens were the same in all groups. The positive rate of SPT in CRSwNP was higher than that in CRSsNP, with statistical significance(P<0. 05). The positive rate of SPT in CRSsNP was higher than that of the control group, without statistical significance. The recurrence rate in CRSwNP was higher than that in CRSsNP, with statistical significance. The recurrence rate in the allergen-positive patients was higher than the allergen-negative patients, with statistical significance.

Objective To investigate the curative effect and adverse reaction of caffeic acid (CFA) for leukopenia and thrombocytopenia caused by imatinib in chronic myeloid leukemia (CML) patients.Methods The effect and adverse reactions of CFA for leukopenia or thrombocytopenia induced by imatinib in 42 CML patients were observed.The CFA was admitted by 0.2 g/time,3 times/d,oral.Results 21 cases of 42 CML patients with thrombocytopenia achieved remarkable curative effect after CFA treatment,13 achieved good effect and 8 had no effect.The total effective rate was 81.0 ％ (34/42).While 15 of 28 leukopenia CML patients achieved remarkable curative effect,8 achieved good effect and 5 had no effect.The total effective rate was 82.1％ (23/28).After CFA therapy for 2 weeks,both platelet and white blood cells count were elevated compared with before treatment,the differences were statistically significant (t =2.015,P =0.023,t =1.913,P =0.035).The average onset time of CFA for leukopenia and thrombocytopenia was 2 weeks and no treatment-related adverse reaction was found.Conclusion CFA is an effective and safe auxiliary drug for treatment of imatinib-induce leukopenia and thrombocytopenia in patients with CML.

Objective: To investigate all trans retinoid Acid (ATRA) inhibition of cell growth in human retinoblastoma Y79 cells, and its mechanism. Methods: Antiproliferation effects of ATRA on Y79 cells were determined by 3 H thymidine incorporation. Cell cycle analysis was performed by flow cytometry. JNK phosphorylation was analyzed by Western blot analysis. Results: After 36 h treatment with 10 -6 mol?L -1 ATRA, 3 H thymidine incorporation decreased to 40%, under the same condition, Y79 cells were arrested in G 0 /G 1 and Sub G 1 peak appeared. Curcumin, JNK blocker, blocked the growth inhibition by ATRA. JNK was phosphorylated in 10 to 20 min. Conclusion: JNK phosphorylating mediated ATRA inhibition of apoptosis in Y79 cells. These results suggested that ATRA might have clinical application for treatment of retinoblastoma.

ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

Objective To investigate the effect of AP-2α on the chemoresistance to oxaliplatin of colorectal carcinoma cell and its related mechanism.Methods Plasmid of GV102-AP-2α-RNAi (experimental group) and control plasmid GV102-NC (negative control group) were transfected into HCT-116 using Lipofectamine 2000 respectively.The AP-2α expression levels of mRNA and protein of experimental group,control group and HCT-116 blank group were detected by qRT-PCR and Western blot.Cell proliferation assay was performed using the CCK-8 and the apoptosis assays were preformed with Annexin V-PE Apoptosis Kit.Results The AP-2α expression levels of mRNA and protein both decreased after transfection of AP-2α-RNAi plasmid,moreover,the effect produced by subsequence 1 was the most significant.After treatment by oxaliplatin,AP-2α protein levels increased with time while mRNA did not change significantly.Western blot results suggested that the level of AP-2α protein in experimental group which was maintained in oxaliplatin was lower than the negative control group.CCK-8 results suggested that cell proliferation ability was significantly higher for the experimental group maintained in oxaliplatin [(88±3) ％] than the negative control group maintained in oxaliplatin [(57±3) ％] and the blank group maintained in oxaliplatin [(73t4) ％].Flow cytometry showed that the apoptosis rate of the experimental group maintained in oxaliplatin [(15.07±1.20) ％] was lower than the control group maintained in oxaliplatin [(24.93±0.90) ％] and the blank group maintained in oxaliplatin [(23.71±1.32) ％].Conclusion AP-2α may be related to the sensitivity of colon cancer cells to oxaliplatin.
